What is a terminating resistor and what do you use a terminating resistor for?

A terminating resistor, also known as a terminator, is an essential part of an antenna cable that ensures that no energy is reflected and the signal is not affected. It is used to seal the ends of transmission media and prevent reflections, thus maintaining the integrity of the signal.

Purpose of a terminating resistor

A terminating resistor has the same impedance as the transmission medium and ensures that no reflections occur at the end of the cable. For example, if an antenna cable has an impedance of 75 ohms, the termination resistor should also be 75 ohms to prevent standing waves that could affect the signal.

Preventing reflection

Reflections at the ends of transmission media can lead to loss of signal quality and disruptions in communications. Using a termination resistor with the correct impedance prevents signals from being reflected back, ensuring smooth and reliable signal transmission.
